RICHARD G. PETERS, OF MANISTEE, MICHIGAN.

CIRCULAR SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 306,949, dated October 21, 1884.

Application filed December 1, 1883.

T at whom it may concern..-

Be it known that I, RICHARD G. Pnrnns, of Manistee, in the county of Manistee and State of Michigan, have invented a new and useful Improvement in Machines for Cutting Sidings and Floorings in Strips; and i do hereby declare that the following isa full and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to machines for cutting sidings and floorings in strips; and its object is to so construct such a machine that the work will be done in the simplest, cheapest, and most effective manner.

To the accomplishment of the above the invcntion consists, first, of the use of a vertical saw and two horizontal saws, and oftheir novel arrangement in respect to each other; second, of thenovel arrangement on themachine of the vertical saw, and of the novel means of adjustment employed in connection therewith; third, of the novel arrangement on the machine of the two horizontal saws, and of the novel means of adjustment employed in connection therewith; fourth, of the novel means employed to adj ust thelog-supporting mechanism, and, fifth. of novel means for determining the posit-ion of the log in respect to the saws.

For the better Ulldl rstanding of my invention, and in order that those skilled in the art may know how to make and use the same, reference is herewith made to the accompanying sheets of drawings, which form part of this specification, and in which Figure 1 is a perspective view, with parts broken away, of a machine embodying my improvements, Fig. 2, a side elevation of that portion which supports the saws; Fig. 3, a section on the line 1 of Fig. 1, and Fig. 4 a section on the line 2 of Fig. 2.

Like letters refer to corresponding parts in the several views.

In the drawings, A represents the floor of the millfB a beam of the same, and G 0 two uprights or supports.

Around the upright G is passed a sleeve, D, which moves up and down upon said upright as a guide. At or near its upper end this sleeve D is provided with an outwardly-extending arm, a, which is curved upon its outer end and presses against the upright C, as

(No model.)

shown. Extending downwardly from this arm a are two rods, 1) and c, the one I) having its lower end secured to a projecting arm, 1, formed lower down on sleeve D, and the one 0 being secured at its lower end to a ring, (1, which encircles the upright O and moves thereon.

By means of the construction thus far described the sleeve D; in being raised or lowered, isalways even in its movement. The sleeve D is also provided at the points shown with bracket 0 and guideway E, to each of which are secured suitable journal-boxes, e, in which a shaft, F, has its bearings. This shaft is provided with a pulley, F, around which a suitable driving-belt is passed, said belt serving to connect the machine herein described with anysuitable machinery to impart motion to shaft F. Upon the opposite end of shaft F a vertical circular saw, G, is secured,

this saw being used. to cut the sidings, as

will be described.

Mounted upon the guideway E, and moving on suitable flanges provided on the top and bottom thereof, is a plate, E, movable horizontally, said plate being provided with suitable journal-boxes, 6-, in which is mounted a vertical shaft, I-I, carrying on its lower end the two horizontal saws I I. The shaft H is also provided on its upper end with a pulley, H, over which is passed a suitable driving belt to impart motion to said shaft and to the saws secured to the lower end thereof.

The mechanism employed to obtain the horizontal adjustment of shaft Ti and saws I is as follows:

To the inner face of plate E is secured a projection, 6, provided with screw-threaded hole, through which is passed a screw-threaded rod, 0, said rod having bearing or support at its opposite end in a bracket, 6", secured to inner face of guideway E. 'Upon its end this rod 0 is provided with a ratchet-wheel, e", which meshes with a similar wheel 6 mounted upon the end of another shaft and at right angles to the wheel 0. The shaft to which wheel e is secured is mounted in a bracket, e secured to sleeve D, and has secured to its outer moved along gaideway E by means of screwthreaded rod and in its movement the plate E carries to the position desired the shaft H.

tween which the log is suspended.

and saws lf, secured to the lower end thereof. A brace or stay, f, connects guideway E to ring 12, previously described as passing around upright ('1, to render the movement of these parts even.

The mechanism employed for adjusting the saw (t is as follows:

A vertical screw-threaded rod, f, has its bearing in the arm a and beam 13. On the upper end of this rod, and secured to it, is a large bevel friction-wheel, J, which is rotated by frictional contact with two bC\'Gl-\VllCOlS, 1, mounted upon a shaft, g, and rotated by a pulley, 1", around which a suitable drivingbelt is passed.

Upon the floor A are placed, as shown, tracks K K, upon which a truck or carriage, L, moves, said truck or carriage being provided witlrmechanism for holding the log to be acted upon by saws, also means for revolving said logs, and means for adjusting said logs both longitudinally and transversely, all of which will now be described.

On the top of truck or carriage L, and at one end thereof, is secured a fixed carriage, L.

To the right ofthe fixed carriage L, as shown in drawings, are two rails or guideways, h h, along which a carriage, It, moves. Each of these rails has formed on its inner face a series of ratchet-teeth, i, the objectof which will. be described.

Extending transversely across the carriage L is a shaft, M, mounted in suitable journalboxes, j j. This shaft is provided on one end with a suitable hand-wheel, M, by means of which it is revolved, and at the points shown in Fig. 1 with spiral screw-threads I: 7;, with each of which a ratchet-wheel, I, meshes. These ratchet-wheelsl are each mounted upon the upper end of a vertical shaft, m, which have bearings in the upper face of carriage L and in hangers or brackets 11, suspended beneath said carriage. Upon the lower end of each shaft m is a second ratchet-wheel, 0, which in their revolution mesh with teeth i, formed on rails 7:.

'3y means of the mechanism described in this connection it will be readily understood that, upon the revolution of the shaft M, the JfltCllCl1-Wl1(tOlSZ are caused to revolve by spiral threads 7.:, and with said wheels the wheels 0, mounted upon the lower end of shafts m, which action causes said wheels 0 to mesh with teeth '1? on rails h, and to more the carriage L longt tudinally on said rails.

Mounted upon each of the carriages L and L, and capable of transverse adjustment thereon, is a head-block, N, each of which supports in brackets on its upper face a center, be- These headbloeks move in suitable guideways formed on carriages L and L", and are provided on. the bottom of their inner ends each with a series of ratchet-teeth, (l q, which teeth mesh with ratchet-wheels r r, mounted upon a rod or shaft, 0, now to be referred to. This shaft has bearings, as shown, in extensions of carriages L and If, and in brackets s s, secured to one side of truck or carriage L. It is provided throughoutits entire length with a slot, s, and has secured to it, at the points shown, ratchet-wheels r r and I, said wheels being socured to said shaft by means of ridges or pro- I jections a, with which each is provided on its inner circumference, these ridges entering'the slot s in shaft 0 and causing said shaft to revolve with the wheels. The wheels 1' r, as before mentioned, are employed to obtain the transverse adjustment of head-blocks N, and the one I, when acted upon by the pawl-and lever mechanism now to be described, serves to operate the shaft 0.

Mounted loosely upon the shaft 0, and adjacent to one side of the ratchet wheel t, is an arm, 1*, having pivoted to one side, near its upper end, a pawl, 1:. At a point opposite, upon. the other side of this arm r, is pivoted one end of a lever, r theother end of said lever connecting loosely with a hand-lever, t. This lever i is loosely mounted at its lower end upon a stud, 1!, located at the center of a circle of which the plate .l. is a quadrant. This plate secured to the fixed carriage L at a right angle to the shaft 0, and is provided, as

shown, with a series of teeth, It.

Mounted upon the stud a is an arm, .11, provided near its lower end with a leaf-s n'ing, a", by means of which the upper end of said arm constantly pressed against the plate I. lffpon its upper end the arm It is provided with a pin orpoinha which enters the teeth to of plate I, and also with a knob, 11:", by means of which pin a is withdrawn from said teeth.

Secured to plate I. at the point shown is a stop, .0, which limits the movement of arm a. \Vhen the rod 0 has been operated by lever I and the head-blocks moved to the positions desired, the arm .r is carried to a position di rectly behind said lever, and serves to holdit in position.

Secured to one corner ofearriage L, and in the sameline with the shaft 0, is a plate, 1, similar IOO IIO

in construction to the one 1?, before referred to, but having a greater cireumference. A. red, It, has bearings in this plate and in braek ets 9 1 secured to headblock N, mounted upon fixed carriage L. This rod is provided on its outer end with a crank, y, by means of which passes over the upper edge of plate 1?, and when operated upon by other parts, now to be described. engages with teeth y", with which said plate is provided.

Secured to rod It, near its outer end, are two arms, .5 and .2, the one a extending a short distance above the top of plate I and connected to the one if by means o'fa bolt, 2.

Mounted upon the rod Rand at a point between the arms and .2, is a ratchet-wheel,

'with which a pawl, engages, said pawl being suspended above this wheel between the arms and .z". Suspended between these arms, and at a point directly above the pawl z", is a spring, 2 which presses down on pawl .2, and causes it to perform its work. The bolt .6, which connects arms is and 2 extends a short distance beyond arm and forms a stud which impinges against the L-shaped arm .2 and forces it to engage with teeth 2* on plate I. \Vhen the log has been revolved and caused to occupy the desired position, these parts are placed as shown in Fig. l, and the further revolution of the log prevented.

Having thus fully described the several parts of my invention, what I claim as new therein, and that for which I desire to secure Letters Patent, is

1.
